Re: [Equipment] 900 point to point said by UHF:Without knowing his EIRP or the RX Sens of his equipment I guess I can't really dispute it, and even if I did, it won't do any good. By my estimation the path loss would leave me with a signal of around -88, but I'm making a whole lot of assumptions to calculate that.
You don't need to know his exact EIRP or RX sensitivity. You can genera,lly assume his TX EIRP will be close to the mac 36 dBm allowed and RX sensitivity around -93 if he's placing CPEs out to 7 miles. If the link prediction is -88 dBm, that is only 5 dB of margin, where typically you'll see WISPs use a 15 to 20 dB margin.
Looking at the Ligowave plot, I don't see this in your future. |

| The ligowave plot is 100' lower than the 2.4 ghz link would be. I think the 2.4 would work, but I haven't ran it through ligowave or radio mobile since he's not interested in working with me. He's on a city water tower, so I can't put my own radio up there.
Also, speed isn't super critical. 500kbps would be fantastic. And if it goes out sometimes due to rain fade or bird poop, so be it. It's not a critical link, just something to kill the boredom and monotony when I have to be stuck in the middle of nowhere. |

It's not a critical link, just something to kill the boredom and monotony when I have to be stuck in the middle of nowhere. WISP's are usually hesitant even if that is what you tell them. Reason being is that many people will beg for service, claiming that they just want something better than dialup and it doesn't matter if it is slow or cuts out, but then once they get used to it working, they can be big pains in the a$$ every time it glitches and seem to forget what they said 6 months ago when it was installed. Also, having a customer with low signal on the tower will reduce the capacity of the entire tower, which is probably the main reason for the distance limit. He's probably just learned that is around the distance limit that has worked well for him.
It's a tough situation. I have some potential customers that I have turned away. There is a possibility they would have perfect signal and never have any problems, but then again I have been burned by it enough times before that I just don't have enough time in a day to be constantly troubleshooting those connections. I find that about 5% of my customers take up 80% of my time. |

Have you considered becoming your own ISP? Your situation is what led me to start my own WISP. |

Sounds like my neighbour... WISP hooked him up in Winter... come Spring the trees leafed out and the whining began. I told him he needed to cut down a few trees but all he would do is call the WISP and ream them out, refuse to pay his bill, etc.
One day he got a call from Bell offering to hook him up to DSL. DSL was not available but the call centre in India didn't know that. The neighbour told the WISP what he could do with their CPE (anatomically impossible) and waited for the Bell tech that never came. Having burned his bridge, he was back on dialup.

No. The town I live in has 4 broadband providers, they don't need a 5th. The location I want access at is literally in the middle of a cornfield 10 miles out of town. Within 4 miles there might be 20 houses, and there's terrain issues and lots of trees. I'm on top of a 100' hill with few trees. Add in the fact I have no money for start up, and being a WISP doesn't appeal to me at all.
I had a T1 at this location but due to situations beyond my control, I can't access it anymore. That could change at any time, but I was hoping for a wireless link as an alternate source. This is why I don't care that much about speed/reliability as I'll likely have the T1 available as well. The firewall sucks, and I'd like to be able to VPN into my home LAN which isn't allowed on the T1. |
